Performance spikes

Hi!

I’m developing an endless-runner type of game for mobile, and i get very inconsistent performance, it often drops 10-15 FPS and looking at the profiler, i’m still not any closer to the solution:

as you can see every 15-40 frames, i get a spike, which is 2-3 frames long, whereas, on average the CPU and GPU renderer need about 1/4 less time, i’m far from instantiating objects this often, so i have little to no idea what is causing the problem. Any help would be really appreciated.

Turn off the V-Sync.
